To calculate the volume of earth masses, you need to use a layer plan with an existing and designed system. One of the two foundations. Such a plane is in the level of each layer in the area covered by earthworks.
Determinations on the set for calculating the volume of earthworks by the method of layer.
The volume of solids between successive planes in the level of layer is calculated by multiplying the average from the sum of their surface through a distance (shock) layer according to the pattern:
in which: P1 and P2 - surface area at the level of neighboring layers, K - layer distance.
The total volume of earth masses from excavations and embankments is calculated by multiplying the sum of the surface through the layer of layers.
To calculate the surface of the fields designated by the layers. The places of contact of the lines of layers designed with existing ones are marked by zero points, and the line connecting these points creates the limit of the earthworks area.
The layer method can be used to calculate the volume of earth masses in equalized areas, Volume volume of widespread spatial excavations, etc..
